Prerequisites

1. Install CentOS 7.7

2. Set up an account to use the Linux Foundation resources. To set up the account, refer to The Linux Foundation website: https://identity.linuxfoundation.org.

3. Set up a Gerrit account and apply an ssh public key. Follow the instructions on the FD.IO wiki web page: https://wiki.fd.io/view/DEV/Setting_up_Gerrit#Log_into_Gerrit

4. Install the following prerequisites packages:

Cli command

yum install -y git cpp gcc rpm-build openssl-devel libmnl-devel numactl-devel epel-release net-tools rdma-core-devel nasm

Installation, Compilation and Configuration

1. Download VPP main master branch.

Cli commands

git clone ssh://<USERNAME>@gerrit.fd.io:29418/vpp.gitgit checkout origin/stable/<"Release_version_number">

Use your Linux Foundation user account name (see Prerequisites above) instead of <USERNAME> as shows in above example.
To find desired <"Release_version_number"> do: "git -r branch" form VPP root git directory.

2. For VPP 18.07 ONLY: Enable the mlx5 PMD driver compilation as follow:

Cli commands


cd /vppsed -i '/vpp_uses_dpdk_mlx5_pmd/s/^# //g' build-data/platforms/vpp.mk

3. Compile and install VPP with DLopen linkage

Cli commands

cd /vppmake install-depmake dpdk-install-dev DPDK_MLX5_PMD=y DPDK_MLX5_PMD_DLOPEN_DEPS=y## Copy manually newly compiled shared module: ##cp /opt/vpp/external/x86_64/lib/librte_pmd_mlx5_glue.so* /usr/lib64/## For VPP 18.07 ONLY, check vpp-dpdk-devel package is installed: ##rpm -qa | grep vpp-dpdk-devel## Compile new binary: ##make build-release vpp_uses_dpdk_mlx5_pmd=yes DPDK_MLX5_PMD_DLOPEN_DEPS=y## Building RPM packages: ##make pkg-rpm vpp_uses_dpdk_mlx5_pmd=yes DPDK_MLX5_PMD_DLOPEN_DEPS=y## Install VPP RPMs: ##rpm -ivh build-root/vpp-sel*.rpmrpm -ivh build-root/vpp-lib*.rpmrpm -ivh build-root/vpp-19*.rpmrpm -ivh build-root/vpp-plug*.rpm

4. Compile and install without DLopen linkage

Cli commands


cd /vppmake install-depmake dpdk-install-dev DPDK_MLX5_PMD=y DPDK_MLX5_PMD_DLOPEN_DEPS=n## Compile new binary: ##make build-release DPDK_MLX5_PMD=y DPDK_MLX5_PMD_DLOPEN_DEPS=n## Building RPM packages: ##make pkg-rpm vpp_uses_dpdk_mlx5_pmd=yes DPDK_MLX5_PMD_DLOPEN_DEPS=n## Install VPP RPMs: ##rpm -ivh build-root/vpp-sel*.rpmrpm -ivh build-root/vpp-lib*.rpmrpm -ivh build-root/vpp-19*.rpmrpm -ivh build-root/vpp-plug*.rpm

5. Edit the /etc/vpp/startup.conf start file to include the following:

Important: Uncomment no-mulit-seg parameter. It disables jumbo packets handling and improves performances significantly.

File

unix {nodaemonlog /tmp/vpp.logfull-coredump}dpdk {dev 0000:07:00.0dev 0000:07:00.1no-multi-segdev default {num-rx-queues 2}}

Insert PCI slot numbers of ConnectX-4/5 interfaces with correct IDs at dpdk { dev } section, as above example.

To verify the correct IDs use:

Cli command


lspci -nn | grep -i mel07:00.0 Ethernet controller [0200]: Mellanox Technologies MT27620 Family [15b3:1013]07:00.1 Ethernet controller [0200]: Mellanox Technologies MT27620 Family [15b3:1013]

6. Start VPP.

Cli command

vpp -c /etc/vpp/startup.conf

7. Enter the VPP Command Line Interface.

Cli command

vppctl

8. Configure L3 interfaces as shown in the example below:

VPP Cli
